Summary
The e-shot™ form builder plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 1.0.2. The eshot_form_builder_update_field_data() AJAX handler lacks any capability checks (current_user_can()) or nonce verification (check_ajax_referer()/wp_verify_nonce()). The function is registered via the wp_ajax_ hook, making it accessible to any authenticated user. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify form field configurations including mandatory status, field visibility, and form display preferences via the eshot_form_builder_update_field_data AJAX action.
